Yes. Deloitte S&O is as picky in selection as the other strategy consultants and are actively trying to expand their strategy practice. The work you do is the same of the Strategy houses. In comparision: I've just been to recruitment events of McKinsey and OC&C and "pure strategy" is estimated to be 25% of their work areas. There is plenty of operational work everywhere.
As an added bonus, they pay more than MBB:
which is like 60% more than a first year analyst in their normal divisions would get.
